X9428 - Single Digitally Potentiometer
The X9428 integrates a digitally controlled potentiometers (XDCP) on a monolithic CMOS integrated microcircuit.
The digitally controlled potentiometer is implemented using 63 resistive elements in a series array.
Between each element are tap points connected to the wiper terminal through switches.
